CHURN.

SPECIFICATION forming part of Letters Patent No. 427,188, dated May 6,1890.

Application filed A t 23, 1889. $erial No. 321,743. (No model.)

To all whom it may concern.-

Be it known that we, JOHN H. REBOK, THOMAS T. lVlAGUIRE, and PHILIP K.REBOK, citizens of the United States, residing at T0- ledo, in thecounty of Tama and State of Iowa, have invented a new and useful Churn,of which the following is a specification.

This invention has relation to that class of churns known asreciprocating dashers, and although herein shown and described for thechurning of butter the same may be employed with equally good resultsfor beating large quantities of eggs.

Among the objects of the invention are to effectually cut and separatethe globules of cream and regulate the temperature of the contents ofthe churn by means of the introduction of cold or warm air for thepurpose of quickly reducing or raising the temperature, as may bedesired, during the operation of churning, and for the purpose ofsecuring the well-known advantageous results; to provide for the readyintroduction of cold or warm air at each upstroke of the piston, and todiffuse such air equally throughout the 0011- tents of the churn; toprovide a convenient motor and means for securing the same in aremovable position over the churn, and to con struct the dasher-disks sothat a thorough separation of the globules shall take place.

lVith these general objects in view the invention consists -in certainfeatures of construction, hereinafter specified, and particularlypointed out in the claim.

Referring to the drawings, Figure 1 is a .perspective of a churnconstructed in accordance with our invention; Fig. 2, a central verticalsection of the same, the motor removed; Fig. 3, a detail in perspectiveof the dashershaft and its disks. Fig. 4: is a bottom perspective of thechurn-body detached.

Like numerals of-reference indicate like parts in all the figures of thedrawings.

1 represents a floor or base, from which rise at triangular pointsstandards 2, the lower ends of which are bolted to the floor or base,and the upper ends of which support a churnsupporting ring 3. Mounted inthe ring is the churn-casting 4, preferably cylindrical or barrelshaped, and provided upon the upper surface of its bottom withupwardly-projecting studs 5.

6 represents the churn proper of cylindrical shape, and of a diameterconsiderably less than the casing, the bottom of the churn beingupwardly convexed or conical, as at 7, and provided at its base withdepending legs 8, terminals of which are concaved, as at 9, to formsockets for the reception of the studs in the bottom of the casing.

10 represents a removable cap for the churnbody, provided at its centerwith a flared opening ll,the cap being preferably threaded and screwedinto position upon the churn-body.

12 represents the dasher-rod, which projects through the flared openingin the cap,

and is provided at its lower end with a conical disk 14:, having a domeor apex 15, and perforated and radial slots 16, formed in its conicalwall. Above the dome and upon the rod 13 is mounted a second disk 17,slightly smaller than the first-mentioned disk, also of a cone shape andprovided with a series of perforations 18. v

The apex of the bottom of the churn-body is provided with anupwardly-projecting valve-chamber 19, having a valve 20, and an opening21 in the upperend of the chamber,

over which is a strainer 22. A pipe 23, suit ably packed, leads from thelower end of the valve-chamber and up to within a short distance of thetop of the churn-body, where by a coupling 24 the same. is connectedwith a flexible pipe-section 25, the opposite end of the section beingadapted for connection with any suitable cold or hot air reservoir.

Any means may be provided for operating the churn-dasher,but we willherein describe a form of construction which we consider best adaptedfor the purpose. 26 represents a rectangular frame, one end of which ishinged to the casing at its upper edge, as at 27, the frame extendingacross and resting upon the opposite edge of the casing and having itsside bars 28 upwardly offset, as at 29, so that the corners 30, formedby the offset, form the four points of contact with the cap or cover ofthe churn-body and serve to aid in retaining the churn in position. Fromthe front end of the frame there depends a hasp 31,

which takes over a staple 32, projecting from the exterior of thecasing, through which a locking-pin may be inserted and the frame boundtightly upon the churn-body. 33 represents an inverted-U-shapedgear-supporting standard, the lower ends of which are bolted, as at 34,to the opposite offsets of the side bars of the frame and are connectedby a transverse bar 35, having a central opening 36 directly over thecentral opening in the cap of the churn-body. Above the transverse barand within the U-shaped standard is journaled a crank-shaft 39, from thecrank portion of which depends a pitman 40, connected by a pin 41 withthe dasher of the churn. A small gear 42 is fixedly mounted at one endof the crank-shaft and meshes with a master-gear 43, mounted upon astub-shaft 45, journaled in one of the branches of the U-standard andprovided with an operating-crank 44. The churn-body is surrounded by asuitable packing of temperature raising or lowering agents, as desired,and the master-gear revolves, which reciprocates vertically thedasher-rod or shaft and its pair of conical-shaped dasher-disks. Thecontents of the churn is caught by the downwardly-moving disk and forcedby the same upon the conical bottom, and around the sides of the diskand through the radial openings therein, and then in contact with thesecond and more finely-perforated disk, where the separation of thecream globules is completed. At each upstroke of the dasher the valve inthe conical bottom is open, and cold or warm air, in accordance with thenecessities of the operation,is drawn in by suction and forced throughthe body of cream at the down- 1 stroke, at the beginning of which thevalve is closed, and in this manner high and low temperatures foraccelerating the converting of the cream to butter are quickly secured.The constant forcing of air through the cream also has a tendency toagitate the same.

Having described our invention, what we claim is The combination, withthe churn-casing, of the churn-body mounted in the casing andsupporting-feet for elevating the body above the bottom of the casing,said body being provided with a conical bottom terminating at its apexin a superimposed valve-chamber provided with upper and lower openings,the lower one forming a valve-seat and provided with aball-valve, anair-pipe leading from the lower opening and up between the casing andchurn, and provided with a flexible pipe adapted for connection with awarm or cold air supply, a reciprocating dasher mounted in thechurn-body, and having a perforated disk at its lower end adapted to fitthe bottom of the body, and having a hollow dome to receive and closeover the valve-chamber, and a second perforated disk mounted upon thedasher above the lower disk, substantially as specified.

In testimony that We claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
